Linux搭建nginx集成環境

前言： Nginx是一個高性能的HTTP和反向代理服務器，本文只是粗略的記錄下配置，不作具體深刻研究

環境：Centos6+

            nginx-1.7.10.tar.gz

            g++、gcc、openssl-devel、pcre-devel和zlib-devel支持環境

一、在安裝nginx前，須要確保系統安裝了g++、gcc、openssl-devel、pcre-devel和zlib-devel軟件。

    安裝必須軟件：

#    yum -y install zlib zlib-devel openssl openssl--devel pcre pcre-devel

*：經過yum的方式自動安裝所需環境軟件

二、檢查系統安裝的Nginx：

#    find / -name nginx

*：yum remove nginx

三、解壓nginx安裝包到指定目錄：

#    tar -zxvf nginx-1.7.10.tar.gz -C /5108/java/

四、進入到/5108/java/nginx-1.7.10目錄下，安裝nginx到指定目錄：

#    ./configure --prefix=/5108/java/nginx

#     make

#    make install

五、修改防火牆配置：

#    vi  /etc/sysconfig/iptables

#添加配置項,過濾80端口
#    -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

#重啓防火牆
#    service iptables restart

六、nginx啓動：

進入sbin目錄下#    ./nginx

    重啓：#    ./nginx -s reload
    關閉：#    ./nginx -s stop

七、設置nginx開機啓動：

1）、建立nginx腳本，並放到/etc/init.d/nginx目錄下，腳本內容以下：

            

#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# it is v.0.0.2 version.
# chkconfig: - 85 15
# description: Nginx is a high-performance web and proxy server.
#              It has a lot of features, but it's not for everyone.
# processname: nginx
# pidfile: /var/run/nginx.pid
# config: /usr/local/nginx/conf/nginx.conf
nginxd=/5108/java/nginx/sbin/nginx
nginx_config=/5108/java/nginx/conf/nginx.conf
nginx_pid=/var/run/nginx.pid
RETVAL=0
prog="nginx"
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0
[ -x $nginxd ] || exit 0
# Start nginx daemons functions.
start() {
if [ -e $nginx_pid ];then
   echo "nginx already running...."
   exit 1
fi
   echo -n $"Starting $prog: "
   daemon $nginxd -c ${nginx_config}
   RETVAL=$?
   echo
   [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx
   return $RETVAL
}
# Stop nginx daemons functions.
stop() {
        echo -n $"Stopping $prog: "
        killproc $nginxd
        RETVAL=$?
        echo
        [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid
}
# reload nginx service functions.
reload() {
    echo -n $"Reloading $prog: "
    #kill -HUP `cat ${nginx_pid}`
    killproc $nginxd -HUP
    RETVAL=$?
    echo
}
# See how we were called.
case "$1" in
start)
        start
        ;;
stop)
        stop
        ;;
reload)
        reload
        ;;
restart)
        stop
        start
        ;;
status)
        status $prog
        RETVAL=$?
        ;;
*)
        echo $"Usage: $prog {start|stop|restart|reload|status|help}"
        exit 1
esac
exit $RETVAL

*：修改其中紅色字體爲本身環境中的路徑

2）、爲nginx腳本添加權限：

#    chmod a+x /etc/init.d/nginx

    *：a+x 爲所賦權限，如"777"

3)、添加nginx服務：

#    chkconfig --add nginx
#    chkconfig nginx on

4）、測試

#    service nginx start    #啓動
#    service nginx stop    #中止
#    service nginx reload    #重啓

*：瀏覽器中輸入ip便可測試是否成功安裝及啓動。

到此，nginx的安裝基本結束，後續再跟進nginx+memcached設置緩存共享和nginx策略基本配置詳解等...
